How to Distinguish from Similar Species: Several other Lepidozona species have distinct longitudinal ridges between the pits on the central areas of the plates.

General Notes and Observations: Locations, abundances, unusual behaviors:
I have encountered this species a number of times clinging to subtidal
objects, especially from the 100 m depth trawls we do in the San Juan Channel.
It is almost always quite small--I have rarely seen it over about 1.5 cm
This closeup of the mantle shows the scattered, oval scales on the dorsal surface, and the spicules which are visible along the mantle margin.
The central areas of the plates have more or less longitudinal rows of shallow pits but the ridges between the pits are not prominent. This is a view of plates 2(left) to 6.
